Playback starts to fastforward with no sound

[tpowell]

I have several HD200's some updated with the latest Beta firmware. It communicates to a SageTV server running V6.6.2.218 on Windows 7 over a 1000bT 1gb) wired network. Recordings are performed with an HD-PVR and HD-5000.

Occasionally (only on certain HD-PVR recorded shows) about 10-15 minutes into the the program the playback starts to "fast forward" at a certain spot. It's like I hit a remote button, but didn't! The fast-forward plays with no audio and would go on indefinitely if I didn't stop it. If I really fast forward a little over the "spot" it will play fine for a few more minutes and then start the same thing again.

I have done some testing and the .mpg video plays back just fine on my Windows 7 SageTV Client and when played directly with WMP.

Any help would be greatly appreciated as this is very frustrating behavior and I have not seen anything quite like this posted in my searches. So far I've had to miss a Caprica and new Southpark due to this issue.
